I've been using serums for ages. They've all had some amount of hyaluronic acid in them but have varied brand - e.g. Aldi, avene, LRP.
I've had awful cystic acne break outs which had got much worse after I switched serum and moisturiser to LRP.
I got totally fed up of teenage skin in my mid 30s. So I decided to ditch the LRP and on a whim picked up a bottle of olay daily care (the cheap one with spf15).
One week in and the lumpy spots have shrunk the redness is gone and the horrible itch that goes with my cystic acne is much reduced.
Could the serums have been making the cystic acne worse? 😬
